Secret key is hardcoded in multiple\u00A0binary files. An attacker who has access to these files can decrypt the communication.\n\nThis issue was fixed in\u00A0IPx series version 6.62.0100.\n\nThe issue STILL EXISTS in End-Of-Life telephone exchanges:\n- CCT-1668 (CCT1CPU)\n- MAC-6400\n-\u00A0CXS-0424\nThese products were discontinued in 2011 and 2012 and and will not receive updates. These products require a hardware update in order to receive a software update. The vendor recommends that users of these devices contact the their service department directly to determine the options for upgrading.","state":0,"publishedAt":"2026-10-15T09:00:35.428+00:00","modifiedAt":"2026-10-15T13:48:28.306+00:00","affected":[{"ecosystem":"Vendor product","name":"IPx","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Slican\",\n                    \"product\": \"IPx\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.62.0100\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"CCT-1668","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Slican\",\n                    \"product\": \"CCT-1668\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"6.56.0430\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"affected\"\n                }"},{"ecosystem":"Vendor product","name":"MAC-6400","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Slican\",\n                    \"product\": \"MAC-6400\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"6.56.0430\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"affected\"\n                }"},{"ecosystem":"Vendor product","name":"CXS-0424","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Slican\",\n                    \"product\": \"CXS-0424\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"6.30.0510\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"affected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:L/SI:N/SA:N","score":8.2,"severity":"HIGH"}],"references":["https://cert.pl/posts/2026/10/CVE-2026-35088"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-35088","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-35088","identifiers":["CVE-2026-35088"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
